Frequently asked questions

Understanding WiFi marketing ROI and benchmarks

How is guest WiFi marketing ROI calculated?

Guest WiFi marketing ROI is calculated by combining two core financial streams: customer acquisition cost (CAC) savings and direct campaign sales revenue. When visitors connect to venue WiFi and opt into marketing, you capture first-party email and phone records at a fraction of paid digital advertising costs (e.g. £1.80 per lead on Google/Meta ads). In addition, automated CRM campaigns trigger targeted emails that drive repeat visits and incremental sales.

What is a typical guest WiFi opt-in rate for physical venues?

Across Purple's network of over 100,000 access points, average opt-in rates range between 10% and 18% of total venue footfall. Higher opt-in rates (18% - 25%) are seen in venues offering seamless captive portal onboarding, social login, or loyalty incentives (such as hotels, shopping malls, and stadiums).

How does guest WiFi replace third-party tracking cookies?

With browser cookie deprecation and privacy features like Apple Private Relay, brands lose visibility on up to 45% of offline visitor activity. Guest WiFi connects physical presence directly to a verified email profile, creating a consented first-party database that operates independently of third-party tracking cookies.

What is the typical payback period for deploying Purple guest WiFi?

Most enterprise and multi-site venues achieve full payback within 3 to 6 months of deployment. The immediate value generated through CAC savings and CRM database expansion typically offsets subscription and hardware costs within the first quarter.

How do automated marketing triggers work with Purple WiFi?

Purple integrates with leading CRMs (including Salesforce, HubSpot, Klaviyo, and Mailchimp). When a guest connects to WiFi, their profile and visit behavior (such as frequency, dwell time, and venue location) are automatically synchronized to trigger personalized welcome emails, review requests, and re-engagement offers.
